SAN JOSE — A southbound Caltrain derailed Monday morning while approaching the Diridon Station in San Jose, an incident that caused delays up to one hour, according to the transit agency.

The train made it to the platform and all the passengers exited normally, according to Caltrain spokesman Alex Eisenhart. There were no injuries reported.

At about 9:05 a.m., train No. 324 experienced a derailment “of one truck of wheels on the last car of the six-car train set while arriving on platform 4 at San Jose Diridon Station,” according to the transit agency. As of 11:15 a.m. Monday, the train had been re-railed.
